OHARLES G. FLIOK, OF TORONTO, ONTARIO, CANADA,

GLASS-POLISHER. i 4

SPECIFICATION forming part of Letters Patent No. 423,'749, dated March 18, 1890. Application filed July 8, 1889. Serial No. 316.779. (No model.)

To all whom it may concern:

Be it known that I, CHARLES G. FLICK, glass beveler, of the city of Toronto, in the county of York, in the Provinceof Ontario, Oanad a, have invented a certain new and useful Improvement in Glass-Polishers, of `which the following is a specification.

The object of the invention is to design a device by which pumice-stone mixed in water may be 'regularly and properly applied to the surfaceof the polishing-wheel; and it consists, essentially, of a tank to contain the mixed pumice-stone and having a revolving mixer and a device by which the pumice-stone is permitted to escape intermittently into a channel, by which it is conveyed to a sponge pressed against the surface of the polishingwheel, the whole being constructed in detail, substantially as hereinafter more particularly explained.

Figure 1 is a perspective view of my de- Vice. Fig. 2 is a detail of the sponge Q and block P.

v A represents an ordinary polishing-wheel, such as is commonly used for the purpose of polishing the beveled edge of a glass-'plate. This wheel is suitablyjournaled in the frame B, and its lower portion is inclosed by a box O. This box I leave without a bottom, but provide a slant-ing spout l), onto which' the surplus pumice falls and is conducted to the pail E.

F is a tank suitably supported, as indicated, above the wheel A.

G is a mixer suitably journaled withintle tank F and caused to revolve by the gearing H. A` hole I is made in the bottom of the tank F, and a spindle J is inserted in the said hole. The head of this spindle effectually stops the hole and prevents the pumice escaping when the spindle is supported by its head, as indicated in the drawings. A spindle K is supported, as indicated, and derives motion from the gearing H. On the outer end of this spindle K a crank L is placed, which crank is suitably connected to the sliding bar M, as shown. On the end of this sliding bar I fix an arm N, which extends be low the bottom end of the spindle J. WVhen the gearing H is put in motion for the purpose of Operating the mixer G, the bar M derives a reciprocating motion, causing the arm N to come in contact with and raise the spindle J every revolution of the spindle K. By thus raising the spindle J so that its head shall be clear of the bottom of the tanka given quantity of the pumice is permitted to escape and fall onto the slanting spout O, which conveys it to the wheel A, as indicated. Immedia'tely below the spout O a block P is fixed, and a sponge Q is attached to the block P and held by the said block against the surface of the wheel A in' such a manner that the pumice falling from the spout O onto the sponge Q is applied to the surface of the wheel A. The surplus pumice falls onto the slanting spout D and is conveyed into the pail E.

From this description it will be seen that a regular supply of pumice is applied to the surface of the wheel A, and it will be observed that whenever it becomes necessary to turn up the surface of the wheel A the pailE and spout D may be removed, when 'the shavings will simply fall through the box C and will not mix or interfere with the pumice.

As it is sometimes necessary to operate the mixer without opening the hole I, I fix the arm N in such a manner that it may be easily turned clear of the end of the spindle J, in which case the mixing mechanism may operate without opening the hole I, or, in other words, without permitting the pumice to escape from the tank.

What I claim as my invention is-- 1. A tank F, provided with a revolving mixer G and having a hole I in its bottom stopped by the vertically-adjustable spindle J, in combination with the spindle K, crank L, sliding bar M, and arm N, arranged substantially as and for the purpose specified.

2. A tank F, provided with a revolving.,

mixer G and having a hole I in its' bottom stopped by the vertically-adjustable spindle J, in* combination with the spindle K, crank L, sliding bar M, arm N, slanting spout O,

and sponge Q, substantially as and for the purpose specified. i
